Electricity

Division 2

In Division 2, the world of metrology rotates around the "electrical triangle" of volt, ohm and ampere - from high-frequency and energy measuring technology to quantum electronics.

Tasks

Electrical quantities are ubiquitous in metrology. The Electricity Division is charged with the realization and dissemination of the electrical and magnetic units. To this end, the Electricity Division develops precision electromagnetic measurements, which are based on electrical quantum metrology and quantum standards nowadays. Nanotechnology is employed and advanced for the in-house fabrication of superconductor and semiconductor quantum standards. Fundamental studies of quantum effects in condensed matter lay the groundwork for the electrical metrology of the future.


The Electricity Division offers various calibration services (see Calibration and Measurement Capabilities) and advises governmental authorities, standardization organizations, and industry on electrical measurements. Knowledge transfer programs support innovation and economic growth.

News

A recently discovered novel solid state material, so called 'topological insulators' (TI), is electrically conductive only at its surface. Thin layers of ferromagnetic TI exhibit quantization of the anomalous Hall resistance without external magnetic field. For the first time, this has now been measured with an uncertainty in the sub-ppm range.
